Normally when we think about drones, we think about drones of the airborne variety. We think about UAVs or unmanned aerial vehicles. That’s not the case with the FrankenDrone, because this happens to be a USV, an Unmanned Surface Vehicle. And that surface just happens to be water.

What you see in the above picture is Robojelly, a robot jellyfish designed by the researchers at Virginia Tech, which could be very useful in the future for underwater surveillance or search and rescue operations. You might be thinking that there is nothing new about a robot inspired by nature, but the robot jellyfish has a new trick up its sleeve. Theoretically, the Robojelly will go on working without ever running out of energy, as long as it’s in water.

If you’ve ever dreamed of flying around with a jetpack, that dream will soon become a reality… if you happen to have $99,500 burning a hole in your pocket. As a quick refresher, the JetLev R200 jetpack straps onto your back, sucking in the surrounding water and spitting it out at such force that you get launched several feet in the air.
